1) find the expected value of that powerball ticket you have.
2) A powerball ticket costs $2. This amount should be higher than the current expected value (the thing you found in question one). That being said, the expected value of a ticket increases as the jackpot value rises. At what jackpot level does the expected value become $2?
3) In class we played the game that if you rolled a 7 or 11 you won $5, and lost $2 otherwise. I want you to design two games. One of them should have an Expected Value that is in favor of the house (the non-player). Another should have an Expected Value that is in favor of the player. These two should be presented in a way where it is difficult to tell the difference. If these games need any tokens, dice, cards, whatever, you should bring them to class for Thursday.
4) In class we discussed the odds for when we roll one die, and when we add up the dots on two dice. Figure out the odds for the sum of:
* 9 when rolling 2 dice
* 10 when rolling three dice
5) I flip a coin five times. What are the chances of me:
* flipping, in order: H, T, H, T, H
* flipping three heads and two tails in any order
* flipping five heads
6) I want you to sample 15 random people on campus and ask them how many credit hours they are currently taking. Bring these values to class on Monday for use.
